Getting Started
The DRV2605L can be used as a demonstration or evaluation tool. When the DRV2605LEVM-CT is
powered on for the first time, a demo application automatically starts. To power the board, connect the
DRV2605LEVM-CT to an available USB port on your computer using the included mini-USB cable. The
demo begins with a board power-up sequence, and then enters the demo effects mode. The four larger
buttons (B1 to B4) can be used to sample haptic effects using both the ERM and LRA motor in the top
right corner. The two smaller mode buttons (“–“ and “+”) are used to change between the different banks
of effects. See the DRV2605L Demonstration Program section for a more detailed description of the demo
application.

Mode 2 – Alerts
Mode 2 showcases the advantages of the smart loop architecture, which includes auto-resonance
tracking, automatic overdrive, and automatic braking.
Figure 9 and Figure 10 show the difference in acceleration when using LRA auto-resonance on and LRA
auto-resonance off. Notice that the acceleration is higher when driven at the resonant frequency. Also,
notice the start and stop time of the acceleration are much quicker when using the overdrive and braking
feature of the DRV2605L.

Acceleration (G)
The reason for higher acceleration can be seen in Figure 11. The LRA has a very-narrow operating
frequency range due to the properties of a spring-mass system. Furthermore, the resonance frequency
drifts over various conditions such as temperature and drive voltage (the effects shown in Figure 11). With
the smart loop auto-resonance feature, the DRV2605L dynamically tracks the exact resonant frequency to
maximize the vibration force.
Frequency (Hz)
Figure 11. LRA Acceleration versus Frequency over Output Voltage
Figure 12 and Figure 13 show the difference between an ERM with automatic closed-loop overdrive and
braking, and the open-loop library waveform with a predefined overdrive period. The closed-loop version
starts and stops the actuator perfectly and does not drive too long or too short. Automatic overdrive and
braking simplify the design of haptic effects by eliminating the tuning time for actuator startup and stop.

begin playing Matching:
Press any of the large effect buttons.
The game then counts down.
Once the countdown completes, a waveform will play from the LRA and the user must match that
given waveform from the given options list before going to the next waveform match.
• B1 - Play/repeat selected waveform from the options list
• B2 - Cycle through the waveforms in the options list to choose from
• B3 - Selects the guessed waveform (B1) as answer
• B4 - Play/repeat the given waveform
4. After each successfully successful match, the board will buzz from the LRA and count down to the next
given waveform. If the user selects incorrectly, then the ERM will buzz and the game is over. If the
user matches all of the given waveforms, the LEDs will scroll and flash twice.

ROM Library Mode
ROM library effects can be accessed by holding the "+" button until the mode LEDs flash and colored
LEDs flash once.
Once in "Library Mode," the DRV2605L embedded ROM effects can be accessed in sequential order. For
example, with all mode LEDs off, B1 is waveform 1, B2 is waveform 2, and so on. Then when mode LED
M0 is on, B1 is waveform 5, B2 is waveform 6, and so on.
The equations for calculating the mode and button of an effect are:
Mode = RoundDown([Effect No.] / 4)
Button = ([Effect No.] - 1) % 4 + 1
% - is the modulo operator
To change between the 5 ERM libraries and the Johnson Electric (JE) ROM Library:
1. Select mode 31 (11111'b) using the "+" or "–" buttons.
• B1 – Press repeatedly to access ROM libraries 1 through 5 and the JE ROM library. The current
library flashes on the mode LEDs
• B2 – Press to select the LRA ROM library
2. Then use the ROM effects as described previously
Each ERM library was designed for specific actuator behavior. Table 3 describes the actuator properties
that are best suited for each library. Note that the rated and overdrive voltages can be changed using the
rated and overdrive clamp registers in the DRV2605L. The most important parameters to characterize with
your actuator are the rise and brake times.

Figure 21. Audio-to-Haptics Input
The DRV2605L audio-to-haptics feature converts an audio signal to a corresponding haptics waveform.
This can be used to simulate bass in music, or use the audio track of a game to produce haptic effects.
To use audio-to-haptics:
1. Apply an analog line-out audio signal (not PWM) to the AUDIO jack on the left side of the board. The
tip of the inserted male audio plug is applied to the IN/TRIG pin of the DRV2605L. See Figure 21.
NOTE: To get the best performance using a headphone out, the user may need to adjust the
volume, so that the input signal is near, but does not exceed 1.8 Vpeak.
2. In demo mode, select mode 0 (00001’b) using the increment mode button (“+”).
3. In mode 0, press either button B1 or B2 to enable the DRV2605L audio-to-haptics. Buttons B3 and B4
switch to internal trigger mode, play a ROM library effect, and then switch back to audio-to-haptics
mode.
• B1 – Audio-to-haptics using ERM
• B2 – Audio-to-haptics using LRA
• B3 – Switch to internal trigger and play library click effect
• B4 – Switch to internal trigger and play library buzz effect
4. Play music and feel the vibrations of the actuator.
NOTE: Some audio signals are too large or too small and the volume must be adjusted. Adjust
appropriately so that the maximum input voltage is 1.8 V and the bass of the input signal can
be felt on the actuator. The audio input minimum and maximum thresholds can be adjusted
using I2C. See the datasheet for more details.

Measurement and Analysis
The DRV2605L uses PWM modulation to create the output signal for both ERM and LRA actuators. To
measure and observe the DRV2605L output waveform, connect an oscilloscope or other measurement
equipment to the filtered output test points, “OUT+” and “OUT–".

Figure 22. Terminal Block and Test Points
The DRV2605L drives LRA and ERM actuators using a 20-kHz PWM modulated waveform, but only the
frequencies around the LRA resonant frequency, or the ERM DC drive voltage, are relevant to the haptic
actuator vibration. The higher frequency switching content does not contribute to the vibration strength of
the actuator and can make it difficult to interpret the modulated output waveform on an oscilloscope. The
oscilloscope image Figure 23 shows the DRV2605L unfiltered waveform and Figure 24 shows a filtered
version used for observation and measurement.
Figure 23. DRV2605L Unfiltered Waveform
Figure 24. DRV2605L Filtered Waveform
If the DRV2605LEVM-CT filter is not used, TI recommends using a first-order, low-pass filter with a cutoff
between 1 and 3.5 kHz. Figure 25 shows a recommended output filter for use while measuring and
characterizing the DRV2605L in the lab.

ADDITIONAL TERMS AND CONDITIONS, WARNINGS, RESTRICTIONS, AND DISCLAIMERS FOR
EVALUATION MODULES
Texas Instruments Incorporated (TI) markets, sells, and loans all evaluation boards, kits, and/or modules (EVMs) pursuant to, and user
expressly acknowledges, represents, and agrees, and takes sole responsibility and risk with respect to, the following:
1.
User agrees and acknowledges that EVMs are intended to be handled and used for feasibility evaluation only in laboratory and/or
development environments. Notwithstanding the foregoing, in certain instances, TI makes certain EVMs available to users that do not
handle and use EVMs solely for feasibility evaluation only in laboratory and/or development environments, but may use EVMs in a
hobbyist environment. All EVMs made available to hobbyist users are FCC certified, as applicable. Hobbyist users acknowledge, agree,
and shall comply with all applicable terms, conditions, warnings, and restrictions in this document and are subject to the disclaimer and
indemnity provisions included in this document.
2. Unless otherwise indicated, EVMs are not finished products and not intended for consumer use. EVMs are intended solely for use by
technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical
mechanical components, systems, and subsystems.
3. User agrees that EVMs shall not be used as, or incorporated into, all or any part of a finished product.
4. User agrees and acknowledges that certain EVMs may not be designed or manufactured by TI.
5. User must read the user's guide and all other documentation accompanying EVMs, including without limitation any warning or
restriction notices, prior to handling and/or using EVMs. Such notices contain important safety information related to, for example,
temperatures and voltages. For additional information on TI's environmental and/or safety programs, please visit www.ti.com/esh or
contact TI.
6. User assumes all responsibility, obligation, and any corresponding liability for proper and safe handling and use of EVMs.
7. Should any EVM not meet the specifications indicated in the user’s guide or other documentation accompanying such EVM, the EVM
may be returned to TI within 30 days from the date of delivery for a full refund. THE FOREGOING LIMITED WARRANTY IS THE
EXCLUSIVE WARRANTY MADE BY TI TO USER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR
STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE. TI SHALL
NOT BE LIABLE TO USER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES RELATED TO THE
HANDLING OR USE OF ANY EVM.
8. No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which EVMs might be or are used. TI currently deals with a variety of customers, and therefore TI’s arrangement with
the user is not exclusive. TI assumes no liability for applications assistance, customer product design, software performance, or
infringement of patents or services with respect to the handling or use of EVMs.
9. User assumes sole responsibility to determine whether EVMs may be subject to any applicable federal, state, or local laws and
regulatory requirements (including but not limited to U.S. Food and Drug Administration regulations, if applicable) related to its handling
and use of EVMs and, if applicable, compliance in all respects with such laws and regulations.
10. User has sole responsibility to ensure the safety of any activities to be conducted by it and its employees, affiliates, contractors or
designees, with respect to handling and using EVMs. Further, user is responsible to ensure that any interfaces (electronic and/or
mechanical) between EVMs and any human body are designed with suitable isolation and means to safely limit accessible leakage
currents to minimize the risk of electrical shock hazard.
11. User shall employ reasonable safeguards to ensure that user’s use of EVMs will not result in any property damage, injury or death,
even if EVMs should fail to perform as described or expected.
12. User shall be solely responsible for proper disposal and recycling of EVMs consistent with all applicable federal, state, and local
requirements.
Certain Instructions. User shall operate EVMs within TI’s recommended specifications and environmental considerations per the user’s
guide, accompanying documentation, and any other applicable requirements. Exceeding the specified ratings (including but not limited to
input and output voltage, current, power, and environmental ranges) for EVMs may cause property damage, personal injury or death. If
there are questions concerning these ratings, user should contact a TI field representative prior to connecting interface electronics including
input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate
operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the applicable EVM user's guide prior
to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During
normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained
at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass
transistors, and current sense resistors which can be identified using EVMs’ schematics located in the applicable EVM user's guide. When
placing measurement probes near EVMs during normal operation, please be aware that EVMs may become very warm. As with all
electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in
development environments should use EVMs.
Agreement to Defend, Indemnify and Hold Harmless. User agrees to defend, indemnify, and hold TI, its directors, officers, employees,
agents, representatives, affiliates, licensors and their representatives harmless from and against any and all claims, damages, losses,
expenses, costs and liabilities (collectively, "Claims") arising out of, or in connection with, any handling and/or use of EVMs. User’s

or loaned to users may or may not be subject to radio frequency regulations in specific countries.
General Statement for EVMs Not Including a Radio
For EVMs not including a radio and not subject to the U.S. Federal Communications Commission (FCC) or Industry Canada (IC)
regulations, TI intends EVMs to be used only for engineering development, demonstration, or evaluation purposes. EVMs are not finished
products typically fit for general consumer use. EVMs may nonetheless generate, use, or radiate radio frequency energy, but have not been
tested for compliance with the limits of computing devices pursuant to part 15 of FCC or the ICES-003 rules. Operation of such EVMs may
cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may
be required to correct this interference.
General Statement for EVMs including a radio
User Power/Frequency Use Obligations: For EVMs including a radio, the radio included in such EVMs is intended for development and/or
professional use only in legally allocated frequency and power limits. Any use of radio frequencies and/or power availability in such EVMs
and their development application(s) must comply with local laws governing radio spectrum allocation and power limits for such EVMs. It is
the user’s sole responsibility to only operate this radio in legally acceptable frequency space and within legally mandated power limitations.
Any exceptions to this are strictly prohibited and unauthorized by TI unless user has obtained appropriate experimental and/or development
licenses from local regulatory authorities, which is the sole responsibility of the user, including its acceptable authorization.
